C/MRI & Xpressnet • • C/MRI boards require a 5 v regulated power supply with a common ground Each board has an unique address configured using a dip switch. Currently, the corners are addresses 1, 2, 3, & 4. We need to standardize assignment & maintenance of addresses. A maximum of 128 boards is supported. Baud rate for communication is set to 57, 600 A USB to Serial driver is required on the computer Computer connects wirelessly to the Lenz LAN-USB. The Lenz software to support serial connection does not work. The connection is via the IP address of the Lenz device directly which is simpler and works well. We have two laptops configured. Both have the most recent versions of JMRI (3. 2). The CATS 3. 2 compatible files for Designer (2. 33) and CATS (2. 13) are loaded. CATS controls the versioning. CATS versions will always trail JMRI releases. Do not upgrade JMRI until CATS can 6 3/15/2018 support the version.

How it did look 3/15/2018 12

How it looked after reducing DB-20 sensitivity 3/15/2018 13

The Issue The ditzels propagate power correctly but all the ditzels are constantly show ON (occupied) and thus all the blocks between corner modules are ON even when unoccupied. The two short segments on each module function correctly. 3/15/2018 14

Test Desensitizing BD 20 s 3/15/2018 15

The DDCOD • The enhancements associated with the Rev. E design are: 1. Increased sensitivity to resistance across the rails, i. e. actual block occupancy 2. Minimized susceptibility to false occupancy caused by stray pickup from track wiring to other blocks, that may be running closely parallel with the detected block • • Another way of looking at the situation is that Rev. E improves detection performance in the presence of electrical noise and interference from wiring to adjacent blocks. It requires a single +12 Vdc supply rather than the balanced ± 12 Vdc required by the OD. Its sensitivity is easy to adjust with a trim potentiometer, using the monitor LED. Its built-in turn-on delay of. 25 s and turn-off delay of 3. 5 s greatly reduces problems from dirty track and other causes of intermittent contact. 3/15/2018 16

Detection: Next Steps • Link a long segment of flex track and test with a BD 20 to see if long track segments. • Link several (3 -5) passive modules and add a BD 20 to see if long module segments are a problem. These have ballast and multiple wire drops. • Test BD 20 desensitization with a 5 -10 k potentiometer • Repeat the same tests with DDCODs. • Build a sensitometer to determine minimum resistance for detection as described by Chubb. • Buy copies of the Chubb manuals. 3/15/2018 18

Wi. Throttle Issues • Router issues – New Router. Possible settings issues. Some routers require a connection with the internet. – May have corrupted security files on the PCs • Wi. Throttle Dropout – Has been reported in the listserve according to Ken Cameron. Not supposed to be an issue with the most recent version. • Ken Cameron suggested a test to do at each setup. Start a virtual throttle from the laptop and prove it’s stable prior to moving to Wi. Throttle. • The bottom line question is: Is this a JMRI issue or is this a communications issue? • Wi.

Resisted Wheelsets • Begin the planning process • When to we start making these and how? Rail. Fun night? Night at Shacks? Is typically a 2 day process so this is tricky. • We will need written instructions downloadable from the website. • What is the optimal resistance? • How many axles? • What fraction of cars need resistors? Best answer is 100% but that may not be possible. 3/15/2018 20

Designer Training • Shack’s site would be ideal • I can handle 8 -10 people at my house • The good news is that Rodney Black’s documentation is in Word • The bad new it’s 90 pages long • Short 1 hour sessions so people could get started and use the Word document as a reference source seems prefferable 21 3/15/2018

Signal types • The module group standard will be three triangular light G-Type signal with any number of heads. Green on the right. • However, based upon modeler preference, any physical signal type is acceptable. • Electrically, we will only support common anode, lighting one LED or bulb per output. Common anode B&O or PRR signals are find. Bipolar LEDs for searchlights are strongly discouraged. They can be made to work as can common cathode signals but with considerable effort that will come only from the module owner. • We are considering and working on approaches to removable plugs. Currently nothing formal to report 3/15/2018 31

Corner Signals • Certainly lend themselves to ABS (intermediate) signals more than control points • Tipple may even be better without signals given it is commonly close proximity to Tipple West & Upton Throat • Signal location choices are constrained by the location of the gaps • Tomar double headed might be good List price is $49. 70. One on each mainline 3/15/2018 32

Turnouts & Track • Preferably mainline turnouts should be DCC controlled. (from the DCC Accessory Bus). This is especially true for crossovers. • At present we do not have a preference for accessory decoder type. • Turnout Accessory addresses must be controlled and assigned by the Superintendent and recorded • Third track can show occupancy but does not feed occupancy information across a module boundary 3/15/2018 35
